Hammer Mills for Australia

Buhler has supplied two vertical hammer mills to an Australian feed mill which enable it to achieve the higher capacity it needs. The special thing about this project is that the exchange required virtually no building modifications.

Australia is more than just kangaroos, red sand, and opals. The dairy industry "down under" is also thriving. Whether you are talking about brie, camembert, or cheddar, the cheese specialties from Australia are increasingly winning awards and are now entering the world's markets. This is a boom to animal feed producers: As a result of the thriving cheese-making industry, dairy farmers are increas-ingly relying on high-quality dairy cattle feeds from experts. CopRice, for example, reached the limits of its grinding capacity in the feed mill it built only six years ago. As the company did not want to con-vert its existing building, it turned to Buhler for a solution. Today, two hammer mills of type Vertica have replaced the former single-motor horizontal hammer mill without taking up more space. The only difference is their higher capacity, while the existing installations ahead of and after the grinding section have been retained. As a special additional benefit, the new grinding system also generates less noise than the former hammer mill, even when all four motors of the two Verticas are running during grinding.

Higher Return

The CopRice feed mill is located in Cobden, a small town with a population of 1400 south-west of Vic-toria and some 200 kilometers from Melbourne. Cobden mainly grinds wheat, lupins, maize (corn), and barley. The raw materials are conveyed from the existing raw material bins to the two Verticas. Screw conveyors transfer the ground material to an existing chain conveyor, which moves it to the feeding units. As the screw conveyor operates with a slight negative pressure, there is no need for any dust collection filters, fans, or exhaust system. On the one hand, this cuts the installation costs, and on the other hand it reduces the loss of moisture, which in turn translates into a higher product weight and therefore ultimately higher profits. This enables CopRice to recoup its investment in its two universal Buhler Vertica hammer mills which compare favorably with other systems in terms of cost within a very short time. No wonder, then, that the Feed Mill Division of the Cooperative of Australian Rice Farmers opted for the Buhler solution.

Among other activities, CopRice Feeds uses the byproducts obtained from rice processing as a raw material for making high-grade animal feeds. Every week, its three feed mills in Leeton, Tongala, and Cobden produce over 2000 metric tons of feed additives, 4000 tons of pelletized compound feeds, and 1000 tons of litter for livestock and pets.

Higher Grinding Efficiency

Over the past ten years, Australias feed manufacturing industry has undergone radical changes. Many large livestock breeders operate their own feed mills, and the smaller operations have merged into large groups. Despite this change, and also in the face of mounting competition, CopRice Feeds is holding its own in the Australian marketplace. Replacing its old hammer mill by two new Buhler Vertica units was a decisive step for the feed mill in Cobden. Thanks to todays higher grinding efficiency, the mill can now also utilize the full capacity of its existing pelletizing system.
